Sending messages to multiple contacts using Intent

I'm trying to send messages through in built sms app through Intent. Its working fine. Here is my code

public class Main_Act extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    Button startBtn = (Button) findViewById(R.id.button);
    startBtn.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {
            if(sendSMS()) {
                Intent intent = new Intent(Main_Act.this, Sample.class);
                startActivity(intent);
            }
        }
    });
}

protected boolean sendSMS() {
    ArrayList<String> nums = new ArrayList<String>();
    nums.add("111111111");
    nums.add("222222222");
    Log.i("Send SMS", "");
    Intent smsIntent = new Intent(Intent.ACTION_VIEW);

    smsIntent.setData(Uri.parse("smsto:"));
    smsIntent.setType("vnd.android-dir/mms-sms");
    smsIntent.putExtra("address"  ,nums);
    smsIntent.putExtra("sms_body"  , "Test ");

    try {
        startActivity(smsIntent);
        finish();
        return true;
    }
    catch (android.content.ActivityNotFoundException ex) {
        Toast.makeText(Main_Act.this,
                "SMS faild, please try again later.", Toast.LENGTH_SHORT).show();
        return false;
    }
}
}

But the problem is it gets navigated to another activity without clicking send button in sms application. It should goto another activity only after clicking the send button in messaging app. Can anyone help me with this problem, Thanks in advance.

Note: if you want to pass data and type don't call method separately because will delete each other you must pass it in one method

wrong 

smsIntent.setData(Uri.parse("smsto:"));
smsIntent.setType("vnd.android-dir/mms-sms");

true

smsIntent.setDataAndType(Uri.parse("smsto:"),"vnd.android-dir/mms-sms");

Let's clear out a slight misunderstanding in your code: You should not try to start both intents in the same part/run of the code as you do here.

A startActivity will not execute directly going to the activity and then return to the same place in the code when activity execution finishes. In stead it asynchronously queues the intent for execution. Then your code queues another intent for execution. After the current code finishes (in this case when the button onClick() method ends) Android queue mgmt can start picking off the queue. Probably the first intent is executed shortly and then directly overrun by an immediate execution of the second.

So what happens in summary is that you first add one intent to the queue in sendSMS and then add intent 2 to the queue in onClick, before leaving. Now both the intents are executed.

What you need to do is to change the sendSMS code to something like:

Intent smsIntent = new Intent(Intent.ACTION_VIEW);
smsIntent.setData(Uri.parse("smsto:"));
smsIntent.setType("vnd.android-dir/mms-sms");
smsIntent.putExtra("address"  ,nums);
smsIntent.putExtra("sms_body"  , "Test ");
// To force the SMS app to return immediately after sent SMS
smsIntent.putExtra("exit_on_sent", true); 
startActivityForResult(smsIntent, MY_SMS_REQUEST_RESPONSE_CODE);

Note the startActivityForResult() method that indicates that we expect Android to return and the "exit_on_sent" extra, to force a swift return.

MY_SMS_REQUEST_RESPONSE_CODE is just any random code you select to recognize the returning result in the callback method (even if you currently do not expect any other returning results, you may have some in the future).

Next thing to do is to remove the second intent creation and queuing. In stead you implement the following callback method (added to this activity):

@Override
protected void onActivityResult(
        int callbackIdentifier, int resultCode, Intent intent) {
    // Is this the expected sendSMS callback ?
    if (callbackIdentifier== MY_SMS_REQUEST_RESPONSE_CODE) { 
        if (resultCode == RESULT_OK) {
          // Continue where you left off (e.g. execute intent 2)
          Intent intent = new Intent(Main_Act.this, Sample.class);
          startActivity(intent);            
        } else if (resultCode == RESULT_CANCELED) {
            // Error handling/retrying etc
        }
    }
    // Support inherited callback functions
    super.onActivityResult(callbackIdentifier,resultCode,intent);
}
